What if we could capture carbon emissions at low cost, using a common polymer found in dinnerware and utensils? Researchers at UC Berkeley and Stanford have developed a method for using melamine to capture carbon dioxide from smokestacks and vehicle exhaust, with efficiency comparable to more expensive materials. This breakthrough could help achieve net-zero carbon emissions by 2050, and the researchers are exploring ways to improve the carbon capture efficiency even further.
Scientists have developed a simple and low-cost method to break down almost a dozen types of "forever chemicals" known as PFAS, which have contaminated virtually every drop of water on the planet and are associated with certain cancers and thyroid diseases. By using a chemical guillotine and common solvents and reagents, they severed the molecular bonds in PFAS, gradually nibbling away at the molecule until it was gone, leaving behind only safe byproducts. This breakthrough could eventually make it easier for water treatment plants to remove PFAS from drinking water.

Mining has been a crucial part of human civilization for centuries, providing us with the resources we need to build, create and thrive. But with this extraction comes consequences, particularly in the form of mine tailings. Mine tailings are the waste materials left over after the ore has been extracted, and they can have significant impacts on the environment, particularly with regards to climate change. To understand the impact of mine tailings, it's important to first understand the science behind mining. When ore is extracted, the minerals are separated from the rest of the material, leaving behind a mixture of minerals, water, and other substances. This mixture is called tailings, and it can contain harmful chemicals, such as heavy metals, that can leach into the environment. Leading academics in the field, such as Dr. Sara Colombo and Dr. Jian Kang, have studied the environmental impact of mine tailings and have found that they can lead to soil and water pollution, as well as contribute to greenhouse gas emissions. For example, Dr. Colombo's research has shown that tailings dams can release large amounts of methane, a potent greenhouse gas, into the atmosphere. These impacts are a concern for many communities, as well as for the planet as a whole. But despite this, there is hope for a more sustainable future. Researchers like Dr. Jian Kang are working to develop new technologies that can reduce the environmental impact of mine tailings, such as using them as a source of energy instead of just waste.
Carbon dioxide (CO2) is one of the most dangerous greenhouse gases that is causing global warming and climate change. It stays in the atmosphere for much longer than other gases such as methane, which only stays in the atmosphere for about 12 years, while CO2 can remain in the atmosphere for thousands of years. Leading climate scientists such as Dr. James Hansen agree that increasing levels of CO2 in the atmosphere are causing global temperatures to rise, leading to melting glaciers, rising sea levels, and more frequent and intense natural disasters such as hurricanes, droughts, and wildfires. Decarbonization is the process of reducing the carbon footprint of our economy by transitioning from fossil fuels to cleaner, renewable energy sources such as wind and solar. This is crucial in order to prevent dangerous levels of global warming and ensure a sustainable future for generations to come. One promising innovation in the field of decarbonization is carbon capture and storage (CCS), which involves capturing CO2 emissions from power plants and industrial processes and storing them underground. Another is the development of electric vehicles, which produce zero emissions and have the potential to greatly reduce our reliance on fossil fuels. Leading academics in the field, such as Dr. David McCollum, have emphasized the importance of decarbonization in limiting global temperature rise to below 2 degrees Celsius, a threshold beyond which the impacts of climate change would become catastrophic and irreversible.
"Reverse Ocean Acidification: A Solution to Our Carbon Dioxide Problem?" - As carbon dioxide emissions continue to threaten our planet, researchers at MIT may have found an innovative way to remove the gas from ocean water in a cost-effective and efficient manner.

Wildfires can have a lasting impact on the ozone layer, a new MIT study shows. Smoke particles from the Australian "Black Summer" megafire triggered a chemical reaction that depleted ozone by 3-5% at mid-latitudes in the southern hemisphere, with effects reaching as far as Antarctica. The study highlights the need to consider the impact of wildfires on ozone recovery efforts and suggests that as long as ozone-depleting chemicals persist in the atmosphere, large fires could spark a reaction that temporarily depletes ozone.
The world's shift towards electric vehicles to reduce greenhouse gas emissions will require a huge demand for critical metals like lithium, nickel, cobalt, manganese, and platinum.

Batteries are a crucial part of our modern lives, powering everything from our smartphones to our cars. But the production and disposal of batteries have significant environmental impacts, from toxic chemicals and heavy metals to greenhouse gas emissions. Fortunately, there are sustainable options and alternatives to batteries that can help mitigate these negative effects. One such option is kinetic energy, which converts motion into electricity. For example, the piezoelectric effect harnesses energy from pressure, while the triboelectric effect converts friction into electricity. Another alternative to batteries is supercapacitors, which store energy in an electric field rather than a chemical reaction. They charge and discharge quickly and have a longer lifespan than traditional batteries. These sustainable options and alternatives to batteries are being researched and developed by leading academics in the field of materials science and engineering. Dr. Jennifer Lewis, a professor of biologically inspired engineering at Harvard University, is leading a team that is working on creating 3D-printed energy storage devices using a hydrogel-based ink. Meanwhile, Dr. Yi Cui at Stanford University is researching how to improve the energy density and safety of solid-state batteries. By exploring academic topics like materials science and engineering, students can learn about the properties of different materials and how they can be manipulated to create sustainable technologies. You can also learn about the environmental impact of technology and how sustainable alternatives can mitigate these effects. In conclusion, sustainable alternatives to batteries offer exciting opportunities for innovation and environmental sustainability. By exploring academic topics related to these technologies, high school students can gain a deeper understanding of the scientific principles behind sustainable energy and contribute to a more sustainable future.

As a society, we rely heavily on oil, but this addiction has led to environmental disasters like oil spills. However, nature has a way of cleaning up after us. Microbes, tiny bacteria that evolved to take advantage of oil and gas seeping from the sea floor, have been eating up oil spills for eons. In fact, a big bloom of microbes ate most of the 4.1 million barrels of oil spilt by BP's Macondo well in the Gulf of Mexico. These microbes are not only oil-eaters, but they also eat plastics, making them a potential solution to the Great Pacific Garbage Patch. Scientists are working on enhancing microbes' ability to eat oil and plastic, which could help us clean up our messes faster. Learning about these microbes and how they can benefit us is not only intellectually stimulating, but it also has practical implications for our planet's health.
